Hello Bruce,
On all four of our studies, the labels and the annot look similar in the sense
that almost the entire
rh.perirhinal_exvivo.thresh.label was contained within the
rh.entorhinal_exvivo.thresh.label (screenshot of the
right hemisphere with labels and annot attached for your reference). The
resulting annot label shows an extremely
under-represented perirhinal on the right hemispheres. The left hemispheres did
not show such a dramatic overlap.
Cheers,
Yi-Leng

Do the labels look better than the annot?

Hello FreeSurfer team,
Thank you for providing the recon-all patch. We have applied this to four
studies and have seen a
notable difference between in the representation of entorhinal over perirhinal
on the right hemisphere
labelling on each analysis ran. The left hemisphere appears to have less
overlap.
I have attached a screenshot of both hemispheres to demonstrate. Would really
appreciate any feedback.
Thanks!
Cheers,
Yi-Leng

thanks. It is almost certainly a bug in recon-all. I'm testing a fix
tomorrow and hopefully we can have one out to you (and the rest of the
list) by tomorrow.
Sorry!
